The structure's design must comply with the general design principles found in the Eurocodes, which inform the Bbl regulations.

A. Structural Safety and Load Combinations

All structures must be designed to withstand all forces during use and execution, and to prevent progressive collapse (disproportionate damage in the event of an accident),,.

• Verification Basis: Verification of the ultimate limit state (ULS) is based on Eurocode (EN 1990),,,,.

• Load Combinations: Structural non-failure verification involves using fundamental load combinations (normal use conditions),, and exceptional load combinations (e.g., resulting from fire, impact, or explosion),,.

B. Optimal Foundations (Geotechnical Requirements)

While the sources do not specify the single "optimal" foundation type (which depends on local soil conditions and logistics), they mandate the methodology for selecting suitable foundations and verifying their performance.

• Geotechnical Design: Design must account for geotechnical aspects (soil, rock, groundwater) in accordance with Eurocode 7 (EN 1997),. Geotechnical investigations are required to establish the ground profile and strength/deformation properties.

• Investigation Depth: The investigation depth must extend to all strata that will affect the project. For piles, this depth is typically down to a level below the lowest point of the pile base,.

• Bearing Resistance and Settlement: The bearing resistance and settlement of spread foundations may be derived using:

    ◦ Semi-empirical or analytical methods from Cone Penetration Test (CPT) results.

    ◦ Standard Penetration Test (SPT) or Dynamic Probing (DP) results in coarse soil, provided local experience or reliable correlations are used,

The structure's operation within the area covered by the Eindhoven Internationale Knoop XL project requires adherence to the Environment Buildings Decree (Bbl), particularly concerning temporary status and relocation.

A. Temporary Structure Classification

A "temporary structure" is defined as a structure with a maintenance period of no more than 15 years at the same location, making your 3-year plan compliant with this definition.

• General Rules: The rules of Chapter 3 (Existing Structures) generally apply to the construction of a temporary structure, unless otherwise specified in Sections 4.2 to 4.7 (New Constructions),. The underlying assumption for structural and health requirements is that satisfying the rules for existing structures (Sections 3.2 to 3.7) is sufficient.

• Specific Requirements (Chapter 4): Key rules from Chapter 4 that specifically apply to temporary structures include provisions related to:

    ◦ Escape Routes and Fire Assistance: Articles 4.65 to 4.71 (course of escape routes) and Articles 4.84 and 4.85 (fire brigade lift/aid post) apply.

    ◦ Ventilation and Flue Gas: The requirements for ventilation/flushing facility capacity (Articles 4.131 and 4.132) and rules regarding flue gas discharge/combustion air supply (Articles 4.135 to 4.141) apply.

    ◦ Sustainability (Thermal): Articles 4.152 (thermal resistance), 4.153 (heat transfer coefficient), and 4.154 (air volume flow) apply, generally setting the minimum requirements at values specified in Table 4.148B,.

B. Relocation Regulations

The relocation of a temporary structure is considered the displacement of an existing structure,.

• Rules for Displacement: When relocating an existing structure in an unchanged composition, the structure must comply with the rules of Chapter 3 (Existing Structures),. For a temporary structure, this rule remains applicable after relocation,.
